Description

顯示裝置Display device

本發明係主張關於2011年03月22日申請之韓國專利案號No.10-2011-0025531之優先權。藉以引用的方式併入本文用作參考。The present invention claims priority to Korean Patent No. 10-2011-0025531, filed on March 22, 2011. This is incorporated herein by reference.

本發明係關於一種顯示裝置。The present invention relates to a display device.

近年來，平面顯示裝置(flat display devices)，如一液晶顯示器(liquid crystal display，LCD)、一電漿顯示面板(plasma display panel，PDP)、或一有機發光二極體(organic light emitting diode，OLED)，取代了傳統陰極射線管(cathode ray tubes，CRTs)，而蓬勃發展。In recent years, flat display devices, such as a liquid crystal display (LCD), a plasma display panel (PDP), or an organic light emitting diode (OLED) ), replacing traditional cathode ray tubes (CRTs), and flourishing.

其中，該LCD係包括：一液晶顯示面板，具有一薄膜電晶體基板(thin film transistor substrate)；一彩色濾光基板(color filter substrate)、及注入該薄膜電晶體基板與該彩色濾光基板之間的一液晶。因該液晶顯示面板係為一非發射型裝置(non-emissive device)，故一背光單元(backlight unit)係被提供於該薄膜電晶體基板之下方，以提供光。自該背光單元所發出之光的穿透率(transmittance)係依據該液晶之配向態(alignment state)而做調整。The LCD system includes a liquid crystal display panel having a thin film transistor substrate, a color filter substrate, and a thin film transistor substrate and the color filter substrate. A liquid crystal between. Since the liquid crystal display panel is a non-emissive device, a backlight unit is provided under the thin film transistor substrate to provide light. The transmittance of light emitted from the backlight unit is adjusted in accordance with the alignment state of the liquid crystal.

該背光單元係依據其一光源之位置而被分為一側發光式背光 單元(edge-illumination type backlight unit)以及一直下式背光單元(direct-illumination type backlight unit)。在側發光式背光單元中，光源係位於一導光板(light guide plate)之一側。The backlight unit is divided into one-side illumination backlight according to the position of one of the light sources An edge-illumination type backlight unit and a direct-illumination type backlight unit. In the side-lit backlight unit, the light source is located on one side of a light guide plate.

直下式背光單元係隨著LCD之尺寸漸大而被發展出來。在直下式背光單元中，至少一光源係被裝設於液晶顯示面板之下方，以提供光給該液晶顯示面板之整體區域。The direct type backlight unit has been developed as the size of the LCD has grown. In the direct type backlight unit, at least one light source is disposed under the liquid crystal display panel to provide light to the entire area of the liquid crystal display panel.

當與側發光式背光單元相比較時，直下式背光單元可應用一大數目的光源，以達到高亮度。但相對地，直下式背光單元便需要比側發光式背光單元更厚的厚度，來確保其亮度均勻性(brightness uniformity)。When compared with a side-lit backlight unit, the direct-lit backlight unit can apply a large number of light sources to achieve high brightness. In contrast, the direct-lit backlight unit requires a thicker thickness than the side-lit backlight unit to ensure its brightness uniformity.

為求解決上述問題，具有複數個可將藍光轉換成紅光或綠光之量子點(quantum dots)之一量子點帶(quantum dot bar)係被設置於發出藍光之一藍光LED之前方。據此，當藍光被照射至量子點帶之上時，藍光、紅光、及綠光係被混合，且該混合光係入射於導光板，進而產生白光。In order to solve the above problem, a quantum dot bar having a plurality of quantum dots capable of converting blue light into red light or green light is disposed before a blue light emitting blue light LED. Accordingly, when blue light is irradiated onto the quantum dot band, blue light, red light, and green light are mixed, and the mixed light is incident on the light guide plate, thereby generating white light.

若該白光係使用該量子點帶而被提供給導光板，則可實現高色彩再現(color reproduction)。If the white light is supplied to the light guide plate using the quantum dot tape, high color reproduction can be achieved.

該背光單元係可包括：一軟性印刷電路板(flexible printed circuit board，FPCB)，提供於該藍光LED之一側，以提供信號及電力給該LED；以及形成於該FPCB之底面下方的一接合件 (bonding member)。The backlight unit may include: a flexible printed circuit board (FPCB) provided on one side of the blue LED to provide signals and power to the LED; and an interface formed under the bottom surface of the FPCB Piece (bonding member).

在藍光自藍光LED發出時，使用經該量子點帶提供給導光板之白光來顯示各種影像之顯示裝置係被廣泛地使用。When blue light is emitted from a blue LED, a display device that displays various images using white light supplied to the light guide plate through the quantum dot tape is widely used.

Therefore, the manufacture of the display device according to the embodiment of the present invention is very simple.

此外，該光源係被插入於該導光件之插入孔，以將該光源牢固地固定在該導光件上。據此，可避免該光源與該導光件分離。也就是說，自該光源所產生之光係有效地入射於該波長轉換裝置中，然後由該波長轉換裝置所轉換過之光可有效地入射於該導光件中。據此，根據本發明實施例之顯示裝置可具有改良之可靠度。Further, the light source is inserted into the insertion hole of the light guiding member to firmly fix the light source to the light guiding member. Accordingly, the light source can be prevented from being separated from the light guide. That is to say, the light generated from the light source is effectively incident on the wavelength conversion device, and then the light converted by the wavelength conversion device can be efficiently incident on the light guide. Accordingly, the display device according to an embodiment of the present invention can have improved reliability.

模框10與背光組件20係構成該背光單元。亦即，該背光單元係包括：模框10以及背光組件20。The mold frame 10 and the backlight assembly 20 constitute the backlight unit. That is, the backlight unit includes a mold frame 10 and a backlight assembly 20.

液晶面板30係被安裝於模框10之中，並排列於光學片500 之上。The liquid crystal panel 30 is mounted in the mold frame 10 and arranged in the optical sheet 500. Above.

液晶面板30係藉由調整通過該液晶面板30之光的強度(intensity)，來顯示影像。亦即，液晶面板30係為一顯示面板，用以顯示影像。液晶面板30係包括：一薄膜電晶體基板(TFT substrate)；一彩色濾光片基板；介於該薄膜電晶體基板與該彩色濾光片基板之間的一液晶層；以及偏振濾光器(polarizing filters)。The liquid crystal panel 30 displays an image by adjusting the intensity of light passing through the liquid crystal panel 30. That is, the liquid crystal panel 30 is a display panel for displaying images. The liquid crystal panel 30 includes: a thin film transistor substrate (TFT substrate); a color filter substrate; a liquid crystal layer interposed between the thin film transistor substrate and the color filter substrate; and a polarizing filter ( Polarizing filters).

如圖5、6所示，發光二極體300與波長轉換裝置400係被插入於插入孔201之中。另外，FPCB 600係接合於導光板200之一頂面上。As shown in FIGS. 5 and 6, the light-emitting diode 300 and the wavelength conversion device 400 are inserted into the insertion hole 201. In addition, the FPCB 600 is bonded to one of the top surfaces of the light guide plate 200.

發光二極體300與波長轉換裝置400可以壓緊契合方式固定於插入孔201之中。也就是說，在後支撐部220與導光部210之間的一間隙(gap)被稍微擴大之後，發光二極體300與波長轉換裝置400係被插入於該間隙。接著，後支撐部220與導光部210之間的間隙又變窄。The light-emitting diode 300 and the wavelength conversion device 400 can be fixed in the insertion hole 201 in a press-fit manner. That is, after a gap between the rear support portion 220 and the light guiding portion 210 is slightly enlarged, the light emitting diode 300 and the wavelength conversion device 400 are inserted into the gap. Then, the gap between the rear support portion 220 and the light guiding portion 210 is narrowed again.

因此，後支撐部220與導光部210可牢固地固定發光二極體300與波長轉換裝置400。Therefore, the rear support portion 220 and the light guiding portion 210 can firmly fix the light emitting diode 300 and the wavelength conversion device 400.

此外，根據本實施例之LCD中，不需要進行額外的接合程序，發光二極體300與波長轉換裝置400便可被固定於導光板200。因此，根據本實施例之LCD可具有很簡易之製造程序。Further, in the LCD according to the present embodiment, the light-emitting diode 300 and the wavelength conversion device 400 can be fixed to the light guide plate 200 without performing an additional bonding process. Therefore, the LCD according to the present embodiment can have a very simple manufacturing process.

又，因發光二極體300係被插入於插入孔201中，並被牢固地固定於導光板200，故可避免發光二極體300與導光板200分離。據此，由發光二極體300所發出之光可有效地入射於波長轉換裝置400，且由波長轉換裝置400所轉換之光可有效地入射於導光板200。另外，自發光二極體300所發出之光的方向可不偏離導光板200。Further, since the light-emitting diode 300 is inserted into the insertion hole 201 and is firmly fixed to the light guide plate 200, the light-emitting diode 300 can be prevented from being separated from the light guide plate 200. Accordingly, the light emitted by the light emitting diode 300 can be efficiently incident on the wavelength conversion device 400, and the light converted by the wavelength conversion device 400 can be efficiently incident on the light guide plate 200. In addition, the direction of the light emitted from the self-luminous diode 300 may not deviate from the light guide plate 200.

因此，根據本實施例之LCD可具有改良之可靠度。Therefore, the LCD according to the present embodiment can have improved reliability.

A section of the C-C' line. In the following, an adhering member will be additionally explained. In addition, the description of the present embodiment can be roughly referred to in the description of the above embodiments.

參閱圖6、7，黏著件460係被設置於波長轉換裝置400之一外表面上。黏著件460係均勻地塗覆於波長轉換裝置400之整體外表面上。亦即，黏著件460係圍繞著波長轉換裝置400。Referring to Figures 6 and 7, the adhesive member 460 is disposed on an outer surface of one of the wavelength conversion devices 400. The adhesive member 460 is uniformly applied to the entire outer surface of the wavelength conversion device 400. That is, the adhesive member 460 surrounds the wavelength conversion device 400.

波長轉換裝置400係包括：一第一表面401；一第二表面402；一頂面403；以及一底面404。The wavelength conversion device 400 includes a first surface 401, a second surface 402, a top surface 403, and a bottom surface 404.

第一表面401係面對發光二極體300，而第二表面402係面對該導光板。此外，頂面403係自第一表面401之一外週緣部分延伸至第二表面402之一外週緣部分；而底面404係面對頂面403。 黏著件460係被設置於第一表面401、第二表面402、頂面403、以及底面404之上。The first surface 401 faces the light emitting diode 300, and the second surface 402 faces the light guide plate. Further, the top surface 403 extends from an outer peripheral portion of the first surface 401 to an outer peripheral portion of the second surface 402; and the bottom surface 404 faces the top surface 403. The adhesive member 460 is disposed on the first surface 401, the second surface 402, the top surface 403, and the bottom surface 404.

黏著件460可被設置於波長轉換裝置400之頂面403與底面404之上。亦即，黏著件460可被設置於波長轉換裝置400與FPCB 600之間。又，黏著件460可被設置於波長轉換裝置400與導光部210之間。另，黏著件460可被設置於波長轉換裝置400與發光二極體300之間。The adhesive member 460 can be disposed over the top surface 403 and the bottom surface 404 of the wavelength conversion device 400. That is, the adhesive member 460 can be disposed between the wavelength conversion device 400 and the FPCB 600. Further, the adhesive member 460 may be disposed between the wavelength conversion device 400 and the light guiding portion 210. In addition, the adhesive member 460 may be disposed between the wavelength conversion device 400 and the light emitting diode 300.

黏著件460係為透明。黏著件460可黏著於波長轉換裝置400之外表面。另外，黏著件460可黏著於發光二極體300與導光板200。詳細而言，黏著件460可黏著於發光二極體300之出射表面與導光板200之入射表面211。Adhesive 460 is transparent. The adhesive member 460 can be adhered to the outer surface of the wavelength conversion device 400. In addition, the adhesive member 460 can be adhered to the light emitting diode 300 and the light guide plate 200. In detail, the adhesive member 460 can adhere to the exit surface of the light emitting diode 300 and the incident surface 211 of the light guide plate 200.

因此，因為黏著件460之存在，空氣層不會形成於發光二極體300與波長轉換裝置400之間。又，因為黏著件460之存在，空氣層不會形成於波長轉換裝置400與導光板200之間。Therefore, the air layer is not formed between the light emitting diode 300 and the wavelength conversion device 400 because of the presence of the adhesive member 460. Moreover, the air layer is not formed between the wavelength conversion device 400 and the light guide plate 200 because of the presence of the adhesive member 460.

黏著件460係被用作為波長轉換裝置400與導光板200之間的光學阻尼作用(optical damping function)。也就是說，黏著件460係可防止波長轉換裝置400與發光二極體300之出射表面之間、以及波長轉換裝置400與導光部210之入射表面211之間形成空氣層。此外，黏著件460可具有與波長轉換裝置400之管體、發光二極體300之填充物(filler)、以及導光板200相近之 折射率。因此，黏著件460可縮小波長轉換裝置400與發光二極體300之出射表面、以及波長轉換裝置400與導光板200之間的折射率差異。The adhesive member 460 is used as an optical damping function between the wavelength conversion device 400 and the light guide plate 200. That is, the adhesive member 460 prevents an air layer from being formed between the wavelength conversion device 400 and the exit surface of the light emitting diode 300, and between the wavelength conversion device 400 and the incident surface 211 of the light guiding portion 210. In addition, the adhesive member 460 may have a similarity to the tube of the wavelength conversion device 400, the filler of the light emitting diode 300, and the light guide plate 200. Refractive index. Therefore, the adhesive member 460 can reduce the refractive index difference between the wavelength conversion device 400 and the exit surface of the light emitting diode 300, and between the wavelength conversion device 400 and the light guide plate 200.

因黏著件460之作用，自發光二極體300所發出之光以及被波長轉換裝置400所轉換之光可有效地入射於導光板200。Due to the action of the adhesive member 460, the light emitted from the light-emitting diode 300 and the light converted by the wavelength conversion device 400 can be efficiently incident on the light guide plate 200.

據此，根據本實施例之LCD可具有改良之亮度。Accordingly, the LCD according to the present embodiment can have improved brightness.

又，黏著件460係具有彈性(elasticity)。而正因黏著件460具有彈性，故黏著件460在波長轉換裝置400與導光板200之間、以及波長轉換裝置400與發光二極體300之間可執行機械阻尼功能(mechanical damping function)。Further, the adhesive member 460 has elasticity. Because the adhesive member 460 has elasticity, the adhesive member 460 can perform a mechanical damping function between the wavelength conversion device 400 and the light guide plate 200 and between the wavelength conversion device 400 and the light-emitting diode 300.

特別是，黏著件460係被塗覆於波長轉換裝置400之外表面上，發光二極體300與波長轉換裝置400係被以壓緊契合方式固定於導光板200之插入孔201中。此時，因黏著件460具有彈性，故在波長轉換裝置400被插入於插入孔201中的時候，黏著件460可有效地保護波長轉換裝置400。In particular, the adhesive member 460 is applied to the outer surface of the wavelength conversion device 400, and the light-emitting diode 300 and the wavelength conversion device 400 are fixed in the insertion hole 201 of the light guide plate 200 in a press-fit manner. At this time, since the adhesive member 460 has elasticity, the adhesive member 460 can effectively protect the wavelength conversion device 400 when the wavelength conversion device 400 is inserted into the insertion hole 201.

特別是，若波長轉換裝置400之管體係由玻璃所製成，則黏著件460可防止管體破裂。In particular, if the tube system of the wavelength conversion device 400 is made of glass, the adhesive member 460 can prevent the tube from being broken.

據此，根據本實施例之LCD之組裝簡易，且可具有改良之機械強度。Accordingly, the LCD according to the present embodiment is easy to assemble and can have improved mechanical strength.

圖10、11係根據本發明第三實施例，繪示有一LCD製造程序 之剖面圖。在下文中，將額外說明一填充件(filling member)。另外，本實施例之說明大致上可配合上述實施例之說明作為參照。10 and 11 illustrate an LCD manufacturing process according to a third embodiment of the present invention. Sectional view. In the following, a filling member will be additionally explained. In addition, the description of the present embodiment can be roughly referred to in the description of the above embodiments.

參閱圖10，發光二極體300與波長轉換裝置400係被插入導光板200之插入孔201中。此時，一預設空間可維持在發光二極體300與波長轉換裝置400之間、以及波長轉換裝置400與導光部210之間。也就是說，發光二極體300與波長轉換裝置400可不需以壓緊契合方式來固定於插入孔201中。Referring to FIG. 10, the light-emitting diode 300 and the wavelength conversion device 400 are inserted into the insertion holes 201 of the light guide plate 200. At this time, a predetermined space can be maintained between the light emitting diode 300 and the wavelength conversion device 400, and between the wavelength conversion device 400 and the light guiding portion 210. That is to say, the light-emitting diode 300 and the wavelength conversion device 400 can be fixed in the insertion hole 201 without being press-fitted.

接著，可硬化樹脂(意指一光硬化樹脂組成物及/或一熱固性樹脂組成物471)係被注入波長轉換裝置400與導光部210之間的空間內。樹脂組成物471可包括環氧樹脂。Next, a curable resin (meaning a photo-curable resin composition and/or a thermosetting resin composition 471) is injected into the space between the wavelength conversion device 400 and the light guiding portion 210. The resin composition 471 may include an epoxy resin.

參閱圖11，將紫外光及/或熱施加於被注入插入孔201中的樹脂組成物471，以硬化樹脂組成物471，進而形成填充件470於插入孔201中。Referring to Fig. 11, ultraviolet light and/or heat is applied to the resin composition 471 injected into the insertion hole 201 to harden the resin composition 471, thereby forming the filler member 470 in the insertion hole 201.

填充件470所進行之功能係與黏著件460大致上相同。The function performed by the filler 470 is substantially the same as the adhesive 460.

根據本實施例之LCD中，可降低波長轉換裝置400之機械性損壞，改善亮度，並增強機械性質。According to the LCD of the present embodiment, mechanical damage of the wavelength conversion device 400 can be reduced, brightness can be improved, and mechanical properties can be enhanced.

圖12係根據本發明第四實施例，繪示有一光源、一導光板、以及一波長轉換裝置之一立體圖；圖13係根據本發明第四實施例，繪示有光源、導光板、以及波長轉換裝置之一剖面圖。在下文中，本實施例之說明大致上可配合上述實施例之說明作為參照。12 is a perspective view showing a light source, a light guide plate, and a wavelength conversion device according to a fourth embodiment of the present invention; FIG. 13 is a diagram showing a light source, a light guide plate, and a wavelength according to a fourth embodiment of the present invention. A cross-sectional view of one of the conversion devices. In the following, the description of the present embodiment can be substantially referred to in the description of the above embodiments.

參閱圖12、13，波長轉換裝置400係被插入形成於導光板200內之一插入孔202中。此時，發光二極體300係被設置於導光板200之一側。也就是說，發光二極體300係被設置於後支撐部220之側。Referring to FIGS. 12 and 13, the wavelength conversion device 400 is inserted into one of the insertion holes 202 formed in the light guide plate 200. At this time, the light-emitting diode 300 is provided on one side of the light guide plate 200. That is, the light emitting diode 300 is disposed on the side of the rear support portion 220.

詳細而言，後支撐部220係被夾在波長轉換裝置400與發光二極體300之間。In detail, the rear support portion 220 is sandwiched between the wavelength conversion device 400 and the light emitting diode 300.

插入孔202可具有一寬度，對應於波長轉換裝置400之一厚度。詳細而言，插入孔202之寬度係與波長轉換裝置400之厚度相等。The insertion hole 202 may have a width corresponding to a thickness of one of the wavelength conversion devices 400. In detail, the width of the insertion hole 202 is equal to the thickness of the wavelength conversion device 400.

發光二極體300所發出之光係經由後支撐部220而入射於波長轉換裝置400。詳細來說，自發光二極體300所發出之光係在光被擴散通過後支撐部220以後，入射於波長轉換裝置400。The light emitted from the light-emitting diode 300 is incident on the wavelength conversion device 400 via the rear support portion 220. In detail, the light emitted from the self-luminous diode 300 is incident on the wavelength conversion device 400 after the light is diffused through the support portion 220.

據此，自發光二極體300所發出之光可不被匯聚於波長轉換裝置400之一局部部分上。因光不被匯聚於波長轉換裝置400之局部部分上，故可避免被包含於波長轉換裝置400中之波長轉換粒子的局部退化(local degradation)。Accordingly, the light emitted from the self-luminous diode 300 may not be concentrated on a partial portion of the wavelength conversion device 400. Since light is not concentrated on a partial portion of the wavelength conversion device 400, local degradation of the wavelength-converting particles included in the wavelength conversion device 400 can be avoided.

此外，後支撐部220係將發光二極體300與波長轉換裝置400相隔開。由此，可防止因發光二極體300所產生之熱能而導致波長轉換粒子之退化。Further, the rear support portion 220 separates the light emitting diode 300 from the wavelength conversion device 400. Thereby, deterioration of the wavelength-converting particles due to thermal energy generated by the light-emitting diode 300 can be prevented.

又，因發光二極體300係與導光板組裝在一起，而與波長轉 換裝置400分開，故根據本實施例之LCD可具有簡易的製造程序。Moreover, since the light-emitting diode 300 is assembled with the light guide plate, and the wavelength is turned The changing device 400 is separated, so that the LCD according to the present embodiment can have a simple manufacturing process.

圖14係根據本發明第五實施例，繪示有一光源、一導光板、以及一波長轉換裝置之一剖面圖；圖15係根據本發明第六實施例，繪示有一LCD之一剖面圖。在下文中，本實施例之說明大致上可配合上述實施例之說明作為參照。Figure 14 is a cross-sectional view showing a light source, a light guide plate, and a wavelength conversion device according to a fifth embodiment of the present invention; and Figure 15 is a cross-sectional view showing a LCD according to a sixth embodiment of the present invention. In the following, the description of the present embodiment can be substantially referred to in the description of the above embodiments.

參閱圖14，導光板200係包括：導光部210；後支撐部220；以及一下部支撐部230。下部支撐部230係被設置於波長轉換裝置400之下方。亦即，下部支撐部230係構成形成於導光板200中的插入孔202底部。Referring to FIG. 14 , the light guide plate 200 includes a light guiding portion 210 , a rear support portion 220 , and a lower portion supporting portion 230 . The lower support portion 230 is disposed below the wavelength conversion device 400. That is, the lower support portion 230 constitutes the bottom of the insertion hole 202 formed in the light guide plate 200.

下部支撐部230可支持波長轉換裝置400之下部。下部支撐部230係直接地與波長轉換裝置400之下部相接觸。下部支撐部230係自導光部210延伸至後支撐部220。下部支撐部230、導光部210、及後支撐部220可為整體成型。此外，導光部210、後支撐部220、及下部支撐部230可圍繞波長轉換裝置400。The lower support portion 230 can support the lower portion of the wavelength conversion device 400. The lower support portion 230 is in direct contact with the lower portion of the wavelength conversion device 400. The lower support portion 230 extends from the light guiding portion 210 to the rear support portion 220. The lower support portion 230, the light guiding portion 210, and the rear support portion 220 may be integrally formed. Further, the light guiding portion 210, the rear supporting portion 220, and the lower supporting portion 230 may surround the wavelength conversion device 400.

又，參閱圖15，下部支撐部230可支撐發光二極體300之下部。詳細而言，發光二極體300與波長轉換裝置400係同步地插入於插入孔201中。此時，下部支撐部230可同步地支撐發光二極體300與波長轉換裝置400之下部。也就是說，下部支撐部230、導光部210、及後支撐部220可同步地圍繞發光二極體300與波長轉換裝置400。Also, referring to FIG. 15, the lower support portion 230 can support the lower portion of the light emitting diode 300. In detail, the light emitting diode 300 is inserted into the insertion hole 201 in synchronization with the wavelength conversion device 400. At this time, the lower support portion 230 can synchronously support the light emitting diode 300 and the lower portion of the wavelength conversion device 400. That is, the lower support portion 230, the light guiding portion 210, and the rear support portion 220 may synchronously surround the light emitting diode 300 and the wavelength conversion device 400.

因下部支撐部230之作用，波長轉換裝置400可輕易地被固定於插入孔202中。亦即，因下部支撐部230支撐波長轉換裝置400，波長轉換裝置400可精確地對準插入孔202。另外，因下部支撐部230之作用，發光二極體300可精確地被固定於插入孔202中。Due to the action of the lower support portion 230, the wavelength conversion device 400 can be easily fixed in the insertion hole 202. That is, since the lower support portion 230 supports the wavelength conversion device 400, the wavelength conversion device 400 can accurately align the insertion hole 202. In addition, the light-emitting diode 300 can be accurately fixed in the insertion hole 202 due to the action of the lower support portion 230.

圖16係根據本發明第七實施例，繪示有一光源、一導光板、以及一波長轉換裝置之一立體圖；圖17係根據本發明第七實施例，繪示有一光源、一導光板、以及一波長轉換裝置之一剖面圖。在下文中，本實施例之說明大致上可配合上述實施例之說明作為參照。16 is a perspective view showing a light source, a light guide plate, and a wavelength conversion device according to a seventh embodiment of the present invention; FIG. 17 is a view showing a light source, a light guide plate, and A cross-sectional view of a wavelength conversion device. In the following, the description of the present embodiment can be substantially referred to in the description of the above embodiments.

參閱圖16、17，導光板200係包括：一第一插入孔202；以及一第二插入孔203。波長轉換裝置400係對準於第一插入孔202，且發光二極體300係對準於第二插入孔203。Referring to FIGS. 16 and 17, the light guide plate 200 includes: a first insertion hole 202; and a second insertion hole 203. The wavelength conversion device 400 is aligned with the first insertion hole 202, and the light emitting diode 300 is aligned with the second insertion hole 203.

第一及第二插入孔202、203可延伸於彼此平行之一方向。此外，第一及第二插入孔202、203可彼此平行。The first and second insertion holes 202, 203 may extend in one of the directions parallel to each other. Further, the first and second insertion holes 202, 203 may be parallel to each other.

導光板200係包括一間隔件240(spacer)。間隔件240係被設置於導光部與後支撐部220之間。又，間隔件240係對準於第一及第二插入孔202、203之間。據此，間隔件240係被設置於發光二極體300與波長轉換裝置400之間。也就是說，發光二極體300係以間隔件240而與波長轉換裝置400彼此相隔而設。The light guide plate 200 includes a spacer 240. The spacer 240 is disposed between the light guiding portion and the rear supporting portion 220. Further, the spacer 240 is aligned between the first and second insertion holes 202, 203. Accordingly, the spacer 240 is disposed between the light emitting diode 300 and the wavelength conversion device 400. That is, the light-emitting diodes 300 are provided apart from the wavelength conversion device 400 by the spacers 240.

因此，間隔件240可避免被包含於波長轉換裝置400中之波長轉換粒子的退化。若發光二極體300係與波長轉換裝置400相鄰，則包含於波長轉換裝置400中之波長轉換粒子可能會因發光二極體300所產生之熱而退化。根據本實施例，發光二極體300係以間隔件240而與波長轉換裝置400彼此相隔而設，故可防止包含於波長轉換裝置400中之波長轉換粒子退化。Therefore, the spacer 240 can avoid degradation of the wavelength-converting particles included in the wavelength conversion device 400.
